DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 627,991, dated July 4,1899.

Application filed September 17, 1898. Serial No. 691,169. N model.)

To all whom, it *ntctg concern:

Be it known that I, CHARLES AMBROSE EN- sIGN,of the city of NewYork,borough of Man hattan, in the county and State of New York, haveinvented anew and useful Improvement in Door-Hangers, of which thefollowing is a full, clear, and exact description.

The object of my invention is to provide a device for hanging slidingdoors and to so construct the device that the door to which said deviceis fitted may be raised and lowered, as occasion may demand, by turningscrews conveniently located at the forward edge of the door. p

A further object of theinvention is to provide a means forexpeditiously, conveniently, and economically hanging doors and afurther object of the invention is to provide two supporting-trolleysfor each door, both of the said trolleys being provided with membersadapted to'be drawn together or separated for the purpose of raising orlowering the door through the medium of the aforesaid screws, thetrolleys being adapted to travel on a particularly-shaped track.

The invention consists in the novel con struction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical longitudinal section taken practically on theline 1 1 of Fig. 2. Fig. 2 is a transverse section taken substantiallyon the line 2 2 of Fig. 1, and Fig. 8is a front elevation of the upperportion of a door having the improvement applied and illustrating theadj usting-heads for the screws acting upon the door. I

A represents -a door which may be of any suitable material, and in theupper surface of the said door a channel or groove 10 is produced,extending nearly from end to end, as illustrated in Fig. 1. In thebottom portion of this groove or channel 10, preferably, two wear-plates11 are secured. The said plates are located at each side of the verticalcenter of the door and each wear-plate is provided with two or morebearings 12. Near the outer end of the wear-plate '11, located near theupper outer vertical edge of the door, an extension 13 .is provided forthe outermost bearing 12, and in this extension a bumper let is secured,which is preferablyv of an elastic material, being adapted forengagement with the opposing door when two doors have been broughttogether. Screws B and B are used in connection with the said door. Thescrew B passes from the front edge of the door loosely through openingsin the bearings 12, terminating justin rear of the first set ofbearings, as shown in Fig. 1, while the second screw B, which isparallel with the screw B, is passed likewise from the front upper edgeof the door and loosely through the front set of bearings 12, and thencelikewise loosely through thesecond set of bearings, each screw beingprovided with suitable collars adjacent to the bearings, which collarsprevent the screws from having end movement. The longer screw B may bemade in one piece or it may be made in two parts connected by a coupling5, as illustrated in Fig. 1, and each screw at its outer end is providedwith a head I), which may be an ordinary screwhead, to receive thescrew-driver, or the said heads may be adapted to receive a wrench or alike tool, if so desired. Each screw is pro vided with a right-hand anda left-hand thread, thethreaded portion of the screw B being between thefirst set of bearings 12, while the threaded portion of the second screwB is-between the second set of bearings 12,

as is also shown in Fig. 1. The threaded portion of each screw isadapted to pass through two traveling blocks 15, one of the said blocksbeing interiorly threaded to receive the righthand portion of the screwand the other block the left hand portion of the same screw. These twoblocks are provided for each threaded portion .of a screw, one set ofblocks being near the front edge of the door and the other set of blocksnear the rear edge of the door. The front set of blocks is provided withopenings through which the second and longer screw B may be looselypassed.

A longitudinal opening 17 is made in the 7 The door is usually providedwith two trolleys D, and a track 18, preferably T-shaped, is locatedabove the upper edge of the door within the door-frame casing, and thetrack 18 is provided with hangers 19, attached to or forming an integralportion of the web 18 of the track, as shown in the drawings. Eachtrolley consists of two spaced housings 20 and 21, a base 22, and apendent arm 23,

attached to the central portion of the base.

The pendent arm 23 of each trolley is engaged at opposite sides by links24 and 25, the links at their lower ends being usually so broughttogether that the lower edge of one of the links may be placed in aposition parallel with yetin advance of the other link, as illustratedin Fig. 2. The pendent arms 23 of the trolleys are pivoted between theupper ends of the links 24 and 25, and the lower ends of the links arepivoted in the slots made in the traveling blocks 15 through the mediumof suitable pins 26. Each housing for the trolley-frame is provided witha peripherallygrooved pulley 27, and the said pulleys are mounted totravel on upwardlypxtending flanges formed upon the upper surfaces ofthe T portions of the rails or tracks, as shown in Fig. 2.

In operation, when it is desired to to raise the door hung with theimproved device if said door is to be raised or lowered at the frontonly the screw B is manipulated through the medium of its head to causethe links 24 and 25, connected with the forward trolley, to be broughttogether or separated. If the adjustment is to be made at the back ofthe door, the screw B is manipulated to bring together or to separatethe links of the rear trolley, but if the door is to be raised equallyat the front and at the rear both screws B and B arecorrespondinglyadjusted.

The hanger is exceedingly simple, durable, and economic and isapplicable to any form of sliding door,and when the improved hanger isapplied the door to which the application is made may be quickly andaccurately ad j usted vertically without disturbing or marring any ofthe woodwork or decorations adjacent to the door.

Having thus described my invention, I

drop or the said screws being adapted for independent operation from oneedge of the door,blocks mounted to travel on the screws, linkconnections between one trolley and the blocks of one screw, and linkconnections between the other trolley and the blocks of the other screw,substantially as shown and described.

2. The combination with a door, a track above the door and front andrear trolleys mounted to move on said track, of two sets of blocksmovably secured to the upper portion of the door, means for adjustingsaid blocks, one set independently of the other set, link connectionsbetween the front trolley and one set of blocks and link connectionsbetween the rear trolley and the other set of blocks, substantially asshown and de scribed.

3. The combination, with a door provided with a channel in its upper.edge, bearings located in the said channel, screws held to turnlooselyin said bearings, the said screws being held against endmovement, each screw being provided with a right and a left hand thread,the right and left hand threaded surface of one screw being near thefront of the door and the corresponding surface'of the other screw nearthe rear of the door, each screw being provided with a thread at theforward vertical edge of the door, whereby each screw may be operatedindependently, a track, trolleys held to travel upon the said track,blocks located upon the threaded surface of each of the screws, oneblock being held to travel on the righthand and the other block on theleft-hand thread of each screw, and links pivotally connecting each pairof blocks with a trolley, as and for the purpose specified.
